    摘要: This invention concerns nanoscale products, such as electronic devices fabricated to nanometer accuracy. It also concerns atomic scale products. These products may have an array of electrically active dopant atoms in a silicon surface, or an encapsulated layer of electrically active donor atoms. In a further aspect the invention concerns a method of fabricating such products. The methods include forming a preselected array of donor atoms incorporated into silicon. Encapsulation by growing silicon over a doped surface, after desorbing the passivating hydrogen. Also, using an STM to view donor atoms on the silicon surface during fabrication of a nanoscale device, and measuring the electrical activity of the donor atoms during fabrication of a nanoscale device. Such products and processes are useful in the fabrication of a quantum computer, but could have many other uses.

    摘要: This invention concerns the fabrication of nano to atomic scale devices, that is electronic devices fabricated down to atomic accuracy. The fabrication process uses either an SEM or a STM tip to pattern regions on a semiconductor substrate. Then, forming electrically active parts of the device at those regions. Encapsulating the formed device. Using a SEM or optical microscope to align locations for electrically conducting elements on the surface of the encapsulating semiconductor with respective active parts of the device encapsulated below the surface. Forming electrically conducting elements on the surface at the aligned locations. And, electrically connecting electrically conducting elements on the surface with aligned parts of the device encapsulated below the surface to allow electrical connectivity and tunability of the device. In further aspects the invention concerns the devices themselves.
